Prod naked figure holding Gorgon’s head (5)
I believe the answer is:
nudge
'prod' is the definition.
('nudge' can be a synonym of 'prod')
'naked figure holding gorgon's head' is the wordplay.
'naked figure' becomes 'nude' (I've seen this before).
'holding' indicates putting letters inside.
'head' indicates taking the first letters.
The first letter of 'gorgon' is 'g'.
'nude' enclosing 'g' is 'NUDGE'.
(Other definitions for nudge that I've seen before include "Push; prompt" , "Light touch or push" , "Gently encourage" , "Poke gently with elbow" , "Slight push" .)
